[Chai Jin cable tray to recommend the star product - bridge] trough cable tray trough cable tray is a fully enclosed cable tray. It is applicable for laying computer cables, communication cables, thermocouple cables and other sensitive systems control cables. It controls shielded cable interference and heavy corrosion in the cable environment protection have good results. Stepped, tray, trough cable tray respective advantages and disadvantages: stepped line bridge with good ventilation performance, no dust, no interference. Trough, tray-line bridge with dust, anti-interference performance. [Chai Jin cable tray to recommend the star product - Bridge] 1.3 tray, trunking and hangers for use in corrosive environments, corrosion-resistant materials should be used for manufacturing rigid. Or take anti-corrosion treatment, anti-corrosion treatment should meet the requirements of the project environment and durability. For corrosion or require higher spraying fire bridge clean place, should use aluminum cable tray. 1.4 bridge in the fire safety requirements of section steel fire tray, cable ladder can be added with a fire-resistant or flame retardant tray performance boards, nets and other material enclosed or semi-enclosed structure. [Chai Jin cable tray to recommend the star product - bridge 2, such as when combined with the power cable tray, power cables and electronic cables should each straight side of the fire bridge wholesale, intermediate diaphragms separated. 3, weak cable combined with other low-voltage cable bridge, should be strictly enforced outer shield choose a weak system of weak cable to avoid mutual interference.
